An mathematical simulation of ionosphere with due regard for its three-dimensional irregularity
Difference methods an approximate solution of a three-dimensional equation of ions diffusion with mixed derivatives and divergence first derivatives are considered. The task is reduced to a chain of three two-dimensional parabolic equations on base of the summary approximation method. Difference operators are constructed, and an analysis of its properties, test calculations and an estimate of a mixed derivatives role are carried out.
